1 Claim. (Cl. 8839) 'Ihis invention relates generally to a magnifyingdevice and is directed in particular to a magv nifying device for use inconnection with transcribing and other copying work, such as in 5recorders offices andthe like. y

The Aprincipal object of my invention is to provide amagnifying devicefor attachment to the horizontal line gauge devices such as of that typesold under the trade name of fLine-a-time. It

" is my purpose to provide such a magnifying device which will magnifyone or more lines of writing immediately above the horizontal line gaugeas commonly employed. My device is constructed for use on any horizontalline gauge which is l5 moved a line at a time-relative to the sheet uponwhich the written matter appears. It is noty requisite of course thatthel line gauge move.

The relative movement may also b'e accomplished by moving the `sheetupon which the written matter appears.

. e A further object of. my linvention is to provide a magnifying devicefor attachment to a horizontal line gauge which device may be adjustedfor proper magniflcation to the eye of the person making thetranscription.

-A further object of the invention is to produce a simple andinexpensive device and yet one which will be exceedinglyY effectivel forthe pur-l pose for which it is designed.

so These objects I accomplish by'means of auchY structure and relativearrangement of parts as `will fully appear by a perusal offthe followingspecication and claim.

In the drawing similar characters of reference indicate correspondingparts in the several views.

Figure 1 is a. front elevation of mydevice asv attached to a-Line-a-time" machine.

vIl'igure 2 is a fragmentary perspective with the magnifying lens insection at one end.

40 Referring 'now more particularly to the ehar-A acters of referenceonthe drawing, the attachment comprises plate like clips I forfrictional engagement with the upper edges of a horizontal line gauge ladjacent its ends, said gauge being as usual in the' form of al stripresting against the sheet B mounted on the holder H of which thegauge-forms apart.- projecting inwardly from' the clip are angers I bentforward at right anglesat'their outer ends, as at 3a. 1

This magnifyinglens is etched orfrosted 5 adjacent its edges for the full lengththereof as In use the device is attached to 'a horizontal line gauge'as' heretofore described and the lensy adjusted by turning the same onitspin connec- 10 tions P and moving the same in or out through themedium of the slots 4b until aline or lines of writing on the sheet Simmediately above the line gauge are visible through the lens, the imageof said line or lines of course bein'g greatly mag- 15 nied, thusfacilitating reading of the same for the purposes of transcription.l

The frosted portion ofthe lens along the edges l prevents undue glare'and also prevents -annoy'- ance from the spherical aberration ordistortion 20 Forvery Vfine writing it may be found desirable to use twoglasses.

From the foregoing description it will be readily seen that I haveproduced such a device as substantially fulfills the objects of theinvention 30 as set forth herein.

While this specification sets forth in detail the present-and preferred.construction of the device,

Hstill'in practice such deviations frbm such detailvmay be resorted toas do not form a departure from the spirit of the invention, as definedby the' appended claim.

Having thus described my invention, lwhat I claim as new andl useful anddesire to secure by o Letters Patent is:

Aline magnifying atta'chmentfor a line gauge device, such deviceincluding a sheet holder and a gauge strip extending across and close tpthe vholder to terminations beyond the same on Vboth 5 sides thereof;said'attachment comprising strips for straddling engagement with thegauge strip beyond the holder, flat elements projecting outwardlyrelative tothe strip formed on the adja-L cent ends of the clips,astrip-like lens disposed m between the elements, holders engaging theends of the lens. and nat elements formed with vthe holden beyond the'ends 'of-the lens ma projecting toward the gauge strip from a plane ad@jacent the frontof the lens and extending across the adjacent faces ofthe clip elements, and.- me'ans 'adjustably connecting said elementstoapwnrruona.
